1) Let's solve this equation, and then check it. Let's find the LCM of 6, 3 which is 6
2) Checking it, we'll have:
(Hard to put it in words for me so here is a picture)
Or you can use point-slope form (
) and insert the slope of -2 and the point (3,6) like this:
And simplify if needed.
Have a great day!
